Google did something similar themselves several years ago as an add-in to internet explorer. It was called web-accelerator or something like that. (correct me if i'm wrong, it might have been for firefox or even chrome itself).

It prefetched links you were likely to click on a website but it had to be abandoned because some GET-links also issued actions, such as removing blog-posts, on way to many web-pages causing havoc.

I fear this will have the same problem.
